CAN DY-MAKIN G MACHINE.

Specification of Letters Patent.

Patented Mar. 24, 1914.

Application filed February 5, 1913. Serial No. 746,292.

To all whom, it may concern:

Be it known. that I, PETER H. SICIILUETER, a citizen of the UnitedStates, and resident of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Candy-MakingMachines, of which the following isa specification, and which areillustrated in the accompanying drawings, forming a part thereof.

The invention relates to apparatus for cooking and mixing such materialas candy and the like and particularly to such apparatus in which thecooking is effected by a gas furnace. The object of the invention is toprovide apparatus in which the parts shall be readily accessible forcleaning and wherein the heating furnace may be quickly moved out ofeffective position, as when it is desired to discontinue or interruptthe cooking operation. I

In the accompanying drawings-Figure 1 shows apparatus of the formprovided by the invention in side elevation. Fig.2 is a detailperspective view showing a form of winding drum which may be employedupon the apparatus, and Figs. 3 and 4 are detail sectional views takenon the lines 3-3 and 4-4, respectively, of Fig. 1.

The parts of the apparatus are preferably associated upon a suitablestandard, as 10. The kettle for containing the material to be treatedisshown at.11 and the furnace is indicated at 12. Each of these parts iscarried by a suitable arm, as 13, 14, which projects horizontallyoutward from the standard, 10. The arm, 13, for supporting the kettle,11, comprises a clamping head, 15, for yoke, 16, forreceiving thekettle.

The arm, 14, is so constructed as to render the Furnace 12, verticallymovable, as for lowering the furnace when it is desired to discontinuethe application of head to the kettle. As shown, the inner end portion,as 17, of the'arm 14, is apertured to run upon the standard 10, andcarries a. gear, 18, for engaging a rack, 19, mounted on the standard.'The gear, 18 is inclosed within a suitable pocket, 20, formed in thepart, 17, of the arm, 14, and is fixed upon a shaft, 21, which isjournaled in the side walls of the pocket, 20. Preferably the shaft 21extends beyond the corresponding side wall of the pocket, 20, at one endand has an op surrounding the standard, 10, and a crating crank, 22,applied thereto. A pawl, 23, pivoted upon the part 17 of the arm, 14,adJacent the gear, 18, cooperates with the gea r to support the arm, 14,in adjusted position.

Preferably the rack, 19, is so constructed as to permit of the arm, 14,being moved to different angular positions about the standard, 10,without the gear, 18, becoming disengaged from the rack. As shown, therack, 19, is loosely held against the side of the standard, 10, ders 24and 25 formed thereon. Movement of the arm,14, about the standardaccordingly serves to cause the rack, 19, to move with it whereby therack 19 and gear 18 are maintained in operative engagement at all tlmes.I

As the kettle, 11, may be of irregular shape commonly found in hand madekettles of the sort employed for cooking candy, provision is made foradjustably moving the furnace, 12 upon the arm, 14, to center it belowthe lowest part of the kettle. As shown, the outer end of the arm, 14,is provided with a vertical aperture, 26, and the under side of thefurnace, 12, is provided with a depending stud, 27, aperture, 26, of thearm, but of less size than the said aperture. A plurality of adjustlngscrews, 28, extend horizontally into the aperture, 26, through theadjacent part of the arm, 14, at different angles. Preferably three ofthe adjusting screws, 28, are employed and these are symmetricallypositioned about the axis of the aperture, 26. By turning the screws,28, in differing amounts, the stud, 27, may be adjustably positionedwithin the aperture, 26, for accurately locatingthe furnace 12, beneaththe kettle, 11.

A vertically disposed stirrer shaft, 29, is preferably employed forentering the kettle, 11, and stirring its contents. As shown, this shaftis slidingly journaled at in a laterally projecting part, 31, of thestandard 10. Av beveled gear splined upon the shaft 29 above the part,31, and resting upon the ournaled bearing, 30, serves for turning thevshaft. The splined connection of the beveled and extends betweenshoulfor entering the gear, 32, with the shaft 29, permits the shaft tobe raised out of the kettle 11, as when the parts are to be cleaned, orthe kettle removed. A winding drum, 33, is provided for raising theshaft 29. As shown, this winding drum is rotatably mounted upon a.

fixed stud, 34, which projects outwardly from the standard, 10. A handcrank, 35, applied to the outer end of the drum, 33, serves for turningthe same. A ratchet, 36, is formed about the inner end portion of thedrum 33, "and a pawl 37, pivotally mount-- 40, mounted upon a side ofthe standard,

10, the guide pulley 39 being located adja-- cent the drum 33, and theguide pulley 40 being located adjacent the outer end of the part, 31,whereby it is substantially in line Yea with the axis of the kettle, 11.A hook, 41, applied to the free end of the cable 38, serves forconnecting the cable with the shaft 29 when the shaft is to be raised.As shown, a collar, 42, is fixed upon the shaft, 29, adjacent its lowerend. This collar has a plurality of apertures, 43, extendingtherethrough, any one of which may serve for re ceiving the hook, 41.Preferably the apertures, 43, are arranged about the shaft, 29, wherebyone of these apertures will be in position for rec'eivingthe hook, 41,irrespective of the angular position occupied by the shaft, 29, when itis brought to rest.

Any convenient means may be employed for turning the, beveled gear, 32,to rotate the shaft, 29. As shown, a motor, 44, is employed for thispurpose. The motor, 44, is mounted upon a shelf, 45, which projectsrearwardly from the standard, 10, adjacent its higher end. Preferablythemotor, 44, serves also to drive a fan, 46, for supplying blast to thefurnace, 12. As shown, the fan is fixed against the under side of theshelf, 45, and is operatively connected to the motor, 44, by a drivingbelt, 47 A blast pipe 48, leads from thefan 46, to furnace 12. Mostdesirably this blast pipe has a flexible section 49 to permit movementof the furnace, 12, incident to its adjustment upon the arm,

14, and to the raising and lowering and swinging of the arm.

A pair of counter shafts, 50, and 51, serve for transmitting power fromthe motor, 44, to the'beveled gear, 32. The counter shaft, 51, isjournaled in horizontal osition in upright brackets 52 and 53, whic risefrom the upper part of the standard, 10, and the arm, 31. This countershaft is equipped at one end with a beveled gear, 54, which meshes withthebeveled gear, 32. A spur car, 55, is loosely mounted on the countershaft 51, adjacent its lower end and a clutch, 56, of usual constructionand controlled by ,a hand lever, 57 serves for operatively connectingthe spur gear, 55, with the counter shaft, whenever. it is desired thatthe stirrer shaft, 29, should be operated'by the motor.

The counter shaft,'56, extends through and 1s journaled in the bracket,53. This counter shaft is equipped with gears, 58, and.

59, upon its opposite ends. The gear 58 meshes with the gear 55, thegear 59 meshes with a gear '60, mounted upon the spindle of the motor,44.

The combination of a kettle and heater with a dasher extending into thekettle and means acting to separate the kettle and heater withoutinterrupting the action of the dasher is not claimed broadly herein forthe reason that such broad claims arereserved for a separateapplication. Claims for the combination of a gas furnace and kettle witha blower supplying the gas furnace, a .dasher for the kettle and unitarymeans for driving the blower and dasher and for the combination of partswhereby the furnace is laterally adjusted upon its supporting arm forcentering it beneath the kettle, are likewise reserved for a separateapplication.
